#Compiler

In part of this post in 2016 @Eduard Lebedyuk asked if anyone knew what is meant by an "expanded class", as referred to in the text that appears when we run the ShowQualifiers classmethod of %SYSTEM.OBJ thus:

SAMPLES>DO $system.OBJ.ShowQualifiers()
...
Name: /checkuptodate
Description: Skip classes or expanded classes that are up-to-date.

Hello, I just noticed that the following query is not allowing when using cached queries.

The compiler will accuse the code about missing a closing quote.
Just so you know, if I use this query dynamically it works, so I guess it's related to the code linting.

I have a class and I would like to dynamically change its selectivity attribute in run-time and then call $system.OBJ.Compile to

recompile the class. I have changed the selectivity to a global, but it seems like it does not work. Any suggestions? Thanks.

Hi, please let me know where i find details on Objectscript internal implementation - is it an interpreted language ? - compiled into binary code (how - which compiler/toolchain ?) ? - support of LLVM ? thanks a lot Frank

The definitions of these two compiler keywords looks very similar to me.

Is there any difference between these two keywords ?

When I declare a parent class as Abstract, its child class could be compiled successfully.

However, when I declare a parent class as NoExtent, some compile errors about storage references get pop up for its child classes.

Thanks.

I’ve hit the wall. I’m a one person shop who wants to start developing Cache on a mac using Eclipse/Atelier, after using Studio for the last 5 years. I’ve installed the 1.1 beta plugin, watched 6 or 7 videos from the September conference, tried several times to work through the cheat sheets, only to have connection issues or compilation issues, so at this point, I’m feeling very frustrated. The videos were interesting, but generally didn’t work as tutorials for fundamental programming operations, for me.

How to understand what's wrong with compilation if the compilator just hides errors?

Compilation started on 05/15/2023 15:58:11 with qualifiers 'cuk'

40 errors, and what do I have to do with this so valuable information?

Hey all,

I have been creating a class to handle file encryption by using GPG keys. I pushed my code out today and my encrypt and decrypt methods weren't working. About a half an hour later in troubleshooting I found out that it needed to be a syntax change. My method has three parameters to it. Examples below:

This is how I was calling it in the test system with no issues:

do gpg.Encrypt()

This is how I was having to call it in my production system to work with no issues:

do gpg.Encrypt("","","")

If I'm using an objectgenerator, is there a way to check the compile flags and have it behave differently based on which flags are set?

And as a tangent, is there a list somewhere of what compile flags there are?

Hello dear developers,

I am currently doing an internship and learning about InterSystems IRIS and ObjectScript and have downloaded and installed the community version of IRIS.

I have not made any changes in the Management Portal.
In Visual Studio Code I have loaded the InterSystems ObjectScript Extension Pack.

If I now want to compile a file, VSC throws an error:
"ERROR #16006: Document name 'x.csp' is invalid"

I'm trying to learn M programing for an Epic db class prerequisite. They said to download the IRIS Studio software to do the testing. I'm having a very difficult time finding information the language. I'm trying to run some examples that Epic has provided (like in below) but the compiler complains that it isn't valid. Of course, it doesn't tell you why it isn't valid.

I'm new to Cache and trying to follow the Using Cache Studio PDF. In section 2.4.3(Adding a Zen form) it tells you insert the following code;

<button caption="Save" o select="zenPage.saveRecord();" />

Unfortunately that code fails compilation. If you try and use the tools there is no o select option nor a select or onselect option. I was wondering if anyone has used this PDF before and knows what the correct attribute should be?
